Coolant

Coolant

The coolant is a important part of keeping your laser tube in optimum operation temperature, which is 14-16C depending on brand and type. Up to 18 is okey-ish for shorter bursts but not recommended for every day use.
A easy solution to keep the coolant cold is to put in frozen plastic bottles of water in your water tank to keep the temperature down.

The best coolant to use is distilled water, it has low contents of minerals and other particles that can cause the coolant to be conductive and disturb the functions of your laser machine.
